When will the movie be in theaters?

Pokemon: Detective Pikachu is scheduled to open in theaters worldwide on May 10.

On May 7, though, Reynolds decided to have some fun with fans online and he retweeted a fake account that claimed to have leaked the entire film, when actually it was a video of looped footage of Detective Pikachu dancing.
